transistor nonlinear model ads

hello everyone

macom sent me the nonlinear model for a transistor i want to make my PA.. the problem is i cant put it in my schematic.. any ideas? it has a lib.defs file that i think i have to use somehow

Install this library in your project environment.In the main toolbar..
Design Kit-->Manage Favorite DesignKits--Add Library Definition File (button)-->(Explore) lib.defs click OK

Then open your project after that DesignKits-->Manage Libraries-->Add Library Definition File ( button)-->(explore ) lib.defs clicl OK
So, the library should be installed as explained above.

thank u so much for the help
